Tungaloy Adds New Threading Inserts and Holders for Swiss Lathe Users

Iwaki, November 2019 — Tungaloy expands its TungThread line of indexable threading tools to include 11ER external threading inserts as well as 8×8 mm and 10×10 mm square shank holders to accommodate the new inserts.

These new 11ER threading inserts and two square shank holders are specifically designed with users of Swiss type automatic lathes in mind. The 11ER insert is smaller than conventional 16ER inserts, and the insert holders are designed to ensure a minimum interference when machined towards the sub-spindle, which is an issue with a 16ER insert holder.

This expansion will enhance the TungThread series to meet the needs of various threading applications on Swiss type automatic lathes and other small-parts manufacturing equipment.
